Scope

This part of ISO 21078 specifies procedures of chemical analysis for the determination of boron(III) oxide used as a binder component added to aluminosilicate refractories, using an acid extraction method. It is applicable for refractories containing less than 1% (mass fraction) of boron(III) oxide.
